摘　　要：将建筑垃圾、废水泥浆再利用,合成复合珊瑚结构材料。利用XRF、BET、SEM、XRD、FTIR对样品进行表征,通过表征实验和吸附等温实验分析其吸附机制。分别探究了固液比、振荡速度、接触时间、初始pH和溶液中磷的初始浓度对吸附量及吸附速率的影响。结果表明,复合珊瑚结构材料对磷的吸附以单层化学吸附为主,填料对磷酸根的吸附容量与填料含量、初始磷酸盐含量呈正相关,与振荡速度呈负相关,pH对平衡吸附量的影响不大,实际最大吸附容量为9.442 mg/g。吸附动力学更符合准二级动力学方程,Langmuir等温线对实验数据的拟合程度更好。Reuse construction waste and waste cement slurry to synthesize composite coral structural materials.The samples were characterized using XRF,BET,SEM,XRD,and FTIR,and the adsorption mechanism was analyzed through characterization experiments and adsorption isotherm experiments.The effects of solid-liquid ratio,oscillation velocity,contact time,initial pH and initial concentration of phosphorus in solution on adsorption capacity and adsorption rate were investigated respectively.The results showed that the adsorption capacity of the composite coral structure materials was mainly a single layer chemical adsorption.The adsorption capacity of the filler was positively correlated with the content of the filler and the initial phosphate content,and negatively correlated with the oscillation velocity.The pH value had little effect on the equilibrium adsorption capacity,and the actual maximum adsorption capacity was 9.442 mg/g.
